I would suggest using juices that are 80/20 or 70/30 with the ego-t. The higher the VG content in the juice, the worse it will be in your Ego-t. Even if you do adjust the wick and that is because of how the atty is constructed. If you use juices other than the ones specified than that will lead to clogging and weak vapor, taste, and TH. Also, the primer goes away after a little bit. As with most other atties. Even if you blow out the primer there will still be a little bit that's in there. All the suggestions above are great. I'm just adding my 2 cents.
